Adhesive sheet strips

Abstract

An adhesive sheet strip for a bond which is redetachable without residue or destruction by extensive stretching in the bond plane, having a pressure sensitive adhesive based on styrene block copolymers, wherein the pressure sensitive adhesive comprises an acid-modified and/or acid anhydride-modified elastomer.

What is claimed is:  
     
         1 . An adhesive sheet strip for a bond which is redetachable without residue or destruction by extensive stretching in the bond plane, having a pressure sensitive adhesive based on styrene block copolymers, wherein the pressure sensitive adhesive comprises an acid-modified and/or acid anhydride-modified elastomer.  
     
     
         2 . The adhesive sheet strip as claimed in  claim 1 , wherein the elastomer is based on SEBS and/or SEPS.  
     
     
         3 . The adhesive sheet strip as claimed in  claim 1 , wherein the elastomer accounts for from 30 to 60% by weight, in particular from 35 to 55% by weight, of the pressure sensitive adhesive.  
     
     
         4 . The adhesive sheet strip as claimed in  claim 1 , wherein the elastomer contains from 1 to 2% of acid groups, based on the overall weight of the elastomer, in particular in the form of incorporated maleic anhydride.  
     
     
         5 . The adhesive sheet strip as claimed in  claim 1 , wherein the pressure sensitive adhesive comprises tackifiers and, where appropriate, further additives, plasticizing agents and/or fillers.  
     
     
         6 . The adhesive sheet strip as claimed in  claim 1 , provided on one side or in particular on both sides with the pressure sensitive adhesive.  
     
     
         7 . The adhesive sheet strip as claimed in  claim 1 , comprising a nonadhesive grip tab.  
     
     
         8 . The adhesive sheet strip as claimed in  claim 1 , comprising only the pressure sensitive adhesive (where appropriate with grip tab) or being a laminate, in particular a laminate having a stretchable backing.  
     
     
         9 . A process for producing an adhesive sheet strip as claimed in claims  1 - 8 , which comprises using a pressure sensitive adhesive as set forth in any of claims  1 - 8 , where appropriate on a stretchable backing.
